Flower  

Flower   Here are a few more photos. Another expert says it's definitely a hibiscus. Thanks so much for your help.

Answer
You may want to refer to internet images if you are still unsure which flower it is. As I answered previously, your photo shows New Guinea impatiens. A hibiscus will have a protruding pistil, a larger,more textured flower, and different foliage color and texture.
